elasticdump import index setting not working

Question

I am able to export index setting using below command

elasticdump --input=http://localhost:9200/tempIndex --output=/Users/Desktop/indexFile --type=settings

but when i tried to import the same setting it is not updating the index setting

The command i used for import is :

elasticdump --input=/Users/Desktop/indexFile --output=http://localhost:9200/tempIndex --type=settings

output of command :

 07:06:33 GMT | starting dump
 07:06:33 GMT | got 1 objects from source file (offset: 0)
 07:06:34 GMT | sent 1 objects to destination elasticsearch, wrote 0
 07:06:34 GMT | got 0 objects from source file (offset: 1)
 07:06:34 GMT | Total Writes: 0
 07:06:34 GMT | dump complete

Below is the settings of my index exported using elasticdump settings option

{
    "tempIndex":{
        "settings":{
            "index":{
                "mapping":{
                    "nested_fields":{
                        "limit":"2000"
                    },
                    "total_fields":{
                        "limit":"2000"
                    }
                },
                "analysis":{
                    "normalizer":{
                        "lowercase_normalizer":{
                            "filter":[
                                "lowercase"
                            ],
                            "type":"custom",
                            "char_filter":[

                            ]
                        }
                    }
                },
                "number_of_shards":"5",
                "number_of_replicas":"1"
            }
        }
    }
}

Settings can only be added on index creation. So the index must not exist when running this command. You can short-circuit by supplying the appropriate URL, but it still would fail due to the fact that you are trying to update non-dynamic settings.

{
    "error": {
        "root_cause": [{
            "type": "illegal_argument_exception",
            "reason": "Can't update non dynamic settings [[index.number_of_shards]] for open indices [[source_index/_OdHe-IVQBemJ3YYka_9hg]]"
        }],
        "type": "illegal_argument_exception",
        "reason": "Can't update non dynamic settings [[ index.number_of_shards]] for open indices [[source_index/_OdHe-IVQBemJ3YYka_9hg]]"
    },
    "status": 400
}

You can do

# passing in _settings path will change operation from insert to update
elasticdump --input=/Users/Desktop/indexFile --output=http://localhost:9200/tempIndex/_settings --type=settings
